thats a very good question. they only allow the 280 as the max engine you can use for the class. but the rules say up to 300 HP but they wont allow the 300 Mercs to run in the class. thats kinda contradicts the rules i dont understand LOL. this is what the rules states for SS Class

It shows NLA in Belgium as well.

The mid sections are much, much stronger on a ROS engine. The 300 mids will snap, and I know this first hand after a hard turn.

destroying the tooling for those motors would amount to one of the dumbest moves ever in the history of the boating industry. the fact that the 200 xs ros are based heavily off of them leads me to bull****.

Maybe but it will create a nice business opportunity for someone.
I have never understood those corporate types who convince themselves that cutting supply to old stuff will mean sales of new engines when all it does is create a new aftermarket business.
Ps I dont think there are many dies in common with a 200xsLast edited by powerabout; 12-25-2014 at 08:31 AM.
